  • Nunzio Giunta, Principal, Giuntabell

    Company logo

    "Giuntabell is a charity and not-for-profit specialist. We are passionate about enhancing the financial performance of our clients. We want them to be exceptional so they can deliver more for their communities. The Sustainable Marketing Services team developed a digital strategy and brand positioning as part of an overall marketing strategy. From a marketing perspective, their focus was on elevating our brand and driving more leads and sales for our company. This involved making sure our brand story came to life through a clear design and content structure. They did a wonderful job at customising the website to our niche audience, talking to what is important to them and their communities. By understanding what our audience’s needs were on their journey through our website, it has been able to build trust and move them to the next stage of having a conversation with us. We have had many positive comments and we have already had some leads come through the new website. Their team is consistently looking at ways to deliver better marketing and better results for us. They are a delight to work with and we feel like they are part of our extended team. We would recommend them to any organisation."

    "Sustainable Marketing Services has delivered an exceptional PR Campaign for the launch of Kiddo- our online babysitting App. Kerryn was able to use her media experience to present a compelling a newsworthy story to media, achieving outstanding national and local media coverage for our business. Media coverage ranged from A Current Affair, Channel 9 News Queensland, Courier Mail, Sunshine Coast Daily and Gold Coast Bulletin. Since our successful PR Campaign, Kiddo has now offer 500 babysitters, 700 plus bookings and thousands of parents registering for the APP. I would highly recommend Kerryn and the team at Sustainable Marketing."

    "The team at Sustainable Marketing Services was excellent. They spent the time needed to really hear our needs, hear who we were and where we were trying to get. They helped us to better understand the market in which our business is operating and how to distinguish (and position) ourselves in this market. The design and web development team from Propeller produced a perfect logo and an outstanding website. We could not be happier with the outcome and with the whole experience. We unreservedly recommend Sustainable Marketing Services."

  • Tyson Dodd, Secretary, Model Aeronautical Association of Australia

    Company logo

    "Our biggest goal when working with Sustainable Marketing Services was to improve our member loyalty and satisfaction. The Sustainable Marketing Services team of marketing and PR professionals have achieved this through our member communications, the creation of our member publication, Wingspan and through social media. Through social media, our members are given the opportunity to participate in their sport on a daily basis. They can basically enjoy their sport 24/7, see what other members are up to and share their love of flying online with our aeromodelling community."

    “Sustainable Marketing has used their industry knowledge and extensive media experience to secure national television coverage with the Today Show on our presence at the Wings over Illawarra Airshow. Maria and Kerryn have gone the extra mile to ensure our media coverage was on brand, provided maximum exposure and highlighted our sport to a wide and broad demographic.

    With a background in Journalism, Kerryn understands how a newsroom operates, knows the best point of contact and how to pitch an engaging story opportunity to media outlets. Their professional work ethic is second to none and their team of media experts are always on the hunt for the next PR opportunity for our organisation.”

  • Kym Ryan, Build Sure Australia

    Company logo

    “We commissioned Maria at Sustainable Marketing Services to create a brand story for our business and build a new website for our company which was compelling, informative information and professional.

    Sustainable Marketing Services developed an excellent digital strategy to bring our brand story to life and to position us for future growth.

    The team at Sustainable Marketing Services was also excellent at coordinating all our staff, obtaining information and taking the overall stress out of the entire process for us.

    We are very happy with the final product. It looks very fresh, is informative, a lot more professional than the previous website and is a lot easy for people to navigate.

    I feel the new website paints a clearer, more accurate picture of our brand. We could not have done this ourselves and feel it was definitely value for money.”

  • Jenny Tsimos, Moreton Bay Beach Lodge

    Company logo

    “Having a small but successful small business in Cleveland, I decided it was time to address my marketing, or lack of it, something that was new to me and somewhat daunting. Thank goodness I discovered Sustainable Marketing and found Maria Anderson who helped and guided me through the process. I am so thrilled with the result for my brand story, promotional material and website and wish I had taken this step earlier! Maria was so prompt, helpful and had so much knowledge to impart with me. I would highly recommend Sustainable Marketing to any future customer.”

  • Brett Coupland, Chief Operations Officer, Sports Aviation Federation of Australia

    Company logo

    “Sustainable Marketing Services has helped us think more strategically about marketing. Their expertise in understanding the marketing of air sports, hang gliding and our members, means that Maria and her team are able to direct our focus to the right activities that perform better- overall it means we get a better ROI.

    During the time that Sustainable Marketing Services has worked with us, I’ve seen the professionalism of our brand improve. The profile of our brand as a safe sport is also increasing.

    Our members have complimented us on our new, professional website, which brings the thrill of pure flight to life. The website adds considerable value to our members with tools and information to help them get the most out of their sport, safely.

    At all times, I can now get on with doing my job as the Chief Operations Officer, knowing that I have an expert marketing team focused on elevating our sport, growing and retaining our membership.

    I like the fact that I know they are committed to continually improving their marketing expertise by making improvements to our marketing strategy, ensuring we have a leading edge and stay at the top of our game.

    Importantly, they understand that we are a NFP and that we need to be prudent with our members’ money. Maria and her team stick to the allocated budget and come up with creative ways to make sure our money goes further.

    Even more important, the team are dedicated, committed to getting us the best results, are a great bunch of people, and act with integrity and honesty. We would recommend Sustainable Marketing Services to other organisations.”

  • Doug Gray, Garwoods Earthmoving

    Company logo

    “Sustainable Marketing Services brought Garwoods’ brand and competitive advantages to life! Now our clients recognise us by our eye-catching visual identity, and they know our service offerings and strengths through our professional corporate brochure and website.

    By taking the time to really get to know our business and our people, Maria Anderson and her team helped us clarify not only our goals, but also our strengths.

    They then used their insights to develop a branding strategy that positions us where we want to be in our market.

    Sustainable Marketing Services identified and harnessed our main competitive advantage – safety – and used it to create a strong visual identity that has helped us “own” the safety category in our industry. Maria helped us integrate the branding across all marketing mediums, including our business cards, our corporate brochure, our website and even our staff clothing. Now all our customers, suppliers and partners recognise us when they see us!

    Our customers love the corporate brochure and website Sustainable Marketing Services has created for us. The balance of facts and figures that support our strengths, the imagery and photos that bring our team to life, and the strong copy that clearly communicates our benefits, is a winning combination.

    Thank-you, Maria and team. Your marketing insights, strategy development and implementation have significantly moved us forward. I would be pleased to recommend you to any business that knows where it wants to go, but doesn’t know how to get there. You make it easy.”
