amy mccormack
founder and managing director

Hello! I’m Amy McCormack. Founder, Business owner and Managing Director of HT and A&A Digital Services Pty Ltd.

My expertise in digital media and operations is as long-standing as the industry itself. For 20+ years, I’ve studied and guided the industry from within Australia’s leading media owner establishments, including Fairfax and ninemsn. My continuing end to end knowledge of the ad operations industry is unique and I’m considered an expert in this complex and dynamic field.

In 2011, I realised that there was a gap in the ad operations market that could also allow highly skilled experts in the field further their careers in a meaningful way, while maintaining their roles as parents and carers. From this idea, I founded HT and A&A Digital Services Pty Ltd.

Today, many years down the track and leading a large team (which includes the foundation employee, Catherine!), we operate a service that shifts and evolves as the market does, and are proud to be the largest and most experienced local media operations support group in Australia.

Ad operations is a constantly changing, exciting industry. We continuously encounter new technologies and challenges. We stay ahead by learning, solving, leading, experimenting and building on our expertise as a team.

I’m incredibly proud to have built our businesses with such an amazing team alongside me, and am excited to continue the journey.

  The best ad ops support person!
