Management, Marketing, PR & Graphic Design

Like every great story, ours is one of hardship, perseverance, spirit and of course, triumph.

Founded by Louise Duff more than 26 years ago, Brilliant Logic has grown from a small consultancy firm with big aspirations into a leading boutique management, marketing, public relations and graphic design agency with an impressive client base spanning iconic Australian events, International fashion heavyweights, not-for-profit organisations and government bodies.

We pride ourselves on providing out-of-the-square solutions, meaning we take the time to ensure that every campaign is perfectly tailored to fit each client’s need. Our passion to craft individually styled outcomes is coupled with a commitment to deliver unrivalled customer service (with a smile). 

There is no problem that we won’t try to help you with. Because when you get Brilliant Logic you get all of us as a team. We are word ninjas, creative types, client focussed, social media addicts, tech savvy, lateral thinking, web design and building geeks, hungry for success and everything that you’ve been looking for.​

Our team of marketing, media and design specialists will bend over backwards to produce highly creative and focused campaigns, offering something that the other agencies can not – an all-hands-on-deck, think tank approach to PR, marketing and design.

Giving Back

According to an ancient legend if you make 1,000 origami cranes you will have a wish granted & will have good luck

We are working on those 1,000 paper cranes, but in the meantime we are trying to make wishes come true in other ways. No, we haven’t constructed an in-house wishing well, but we have built strong philanthropic relationships with a number of worthy community organisations.

Brilliant Logic enjoyed a long-standing relationship with The Salvation Army for many years, providing media consultancy services pro bono to the organisation.

Through our work with The Salvos, we formed a strong working connection with the Oasis Youth Support Network, which saw us manage the Annual Oasis Ball for five consecutive years to raise invaluable funds for this cause.

Brilliant Logic also supported the Central Coast and Hunter Burns Survivor Support. We were proud to assist the Group with its official launch, also developing a logo and corporate suite for the organisation and undertaking all public relations and graphic design services pro bono.

Most recently Brilliant Logic partnered with the Reach Foundation, with our fearless leader providing media training workshops to the hundreds of young people who undertake the Foundation's programs each year.

Our backgrounds in media, marketing, management and graphic design don’t stop us from giving back to the community - regularly donating our time to support local groups and charities that need our help, like the Family Room at Gosford Hospital.



Our portfolio ranges from nationally recognised brands and upmarket boutiques to not for profit organisations, government agencies and everything in between. Here are some iconic brands we have forged relationships with:

Ronald McDonald House Charities
Brilliant Logic is proud to work with Ronald McDonald House Westmead across the areas of social media, communication, marketing and graphic design. The House provides a home away from home for families with seriously ill children receiving treatment at The Children's Hospital at Westmead. Brilliant Logic is helping to share the remarkable stories of families residing in the house.

After protests caused an initial delay, we were retained to work alongside the Department of Premier and Cabinet on the scuttling of the Ex HMAS Adelaide on April 13 2011. Our role was to facilitate and re-engage local, state and national media for the scuttle. What resulted was highly positive national exposure for the event across all target audiences and media outlets.

St Vincents de Paul
Brilliant Logic is proud to be working with St Vincent de Paul Society NSW on two major projects in 2016 – the Hotels Have Hearts Gala Dinner and the Vinnies CEO Sleepout in Sydney, delivering event management and communication/fundraising support respectively. Both events are pivotal to the fundraising efforts of St Vincent de Paul Society NSW, which delivers a range of welfare and support services to community members.

Established in 1976, NAISDA Dance College is Australia’s premier Indigenous training College with a proud tradition of producing the next generation of Aboriginal and Torres Strait Islander performers. Brilliant Logic is currently working with NAISDA in the strategic planning and roll out of the College’s 40th Anniversary marketing – a momentous event for this iconic institute.

In 2012 and 2013, Brilliant Logic was engaged by The Salvation Army to work on the national campaign that would drive donations for its annual Christmas Appeal. In addition, we were engaged to lead the Salvation Army’s 2013 Red Shield Appeal campaign for the Australian Eastern Territory and have done so since then.

We proudly work with McDonald’s across the country. Our work has included facilitation sessions for Licensees and the creation of a Code of Conduct for the Licensees of McDonald’s Australia, which aims to regulate Licensee engagement and foster group cohesion. Our work has seen us retained to provide support and facilitation for McDonald’s Licensees in an ongoing capacity.
