a leading Australian auto consumables supply and sales business
4 December 2025
Alvia Private Capital (“Alvia”) has completed a majority investment in The Automotive Group (“TAG”), a leading Australian auto consumables supply and sales business.
Alvia is investing alongside Managing Director Michael Petersen, who has led TAG since 2009 and has spent more than 30 years with the business. As part of the transaction, Alvia has acquired the full shareholding of TAG Founder Brad Garnham. Michael will continue to lead the company and partner with Alvia to accelerate TAG’s next phase of growth.
TAG’s unique business model includes two core divisions:
TAG has experienced strong growth, with a post-COVID CAGR exceeding 15% per annum.
TAG’s products, its staff and its long-standing dealership relationships combine to create an attractive business with high barriers to entry and consistent, recurring demand. TAG sits squarely in the resilient, cash-generative private market profile at the core of Alvia’s Family Office mandate.
Strong momentum in auto servicing, consumables
Alvia’s investment is underpinned by the robust fundamentals of Australia’s auto servicing and consumables industry. The national auto-parts aftermarket exceeded A$15 billion in 2024 and is projected to grow at around 5% annually through 2033, reaching A$24 billion. The sector’s growth is driven by the expanding national vehicle fleet and the essential role consumables play in dealership profitability.
TAG Managing Director Michael Petersen said,
“For more than three decades we have built the business through enduring dealership relationships, reliable execution and a focus on customer outcomes. This investment comes at an ideal time for the business. It will allow us to expand our national footprint, enhance our operating platform and unlock the next phase of sustained growth. We are excited to partner with Alvia and continue building on the momentum we have created.”
Commenting on the transaction, Founder Brad Garnham said,
“I’m delighted to see TAG begin its next chapter with Alvia. The partnership positions the business for continued success and long-term opportunity”.
David Browne, Partner at Alvia Private Capital said,
“TAG represents Alvia’s second majority transaction in 2025, and marks our partnership with an exceptional management team leading a high growth business with niche market leadership. We remain firmly focused on long-term value creation and look forward to supporting the ongoing success of TAG, its people, and its customers”.
Alvia CEO Nathan Robertson said,
“The TAG investment is another demonstration of Alvia’s aligned investment model, with our employees investing alongside our clients. The business has a differentiated model, a strong track record and a compelling national rollout strategy. It is exactly the type of resilient, high quality business we aim to partner with, and we are confident it will deliver strong outcomes for our clients”.
