Australia’s competition watchdog, the Australian Competition and Consumer Commission (ACCC), has formally blocked US-based MicroStar Logistics LLC from acquiring the assets of its only direct rival, Konvoy Holdings Pty Ltd.
MicroStar, which operates in Australia under the brand name Kegstar, and Konvoy represent the country’s only two suppliers of keg pooling services. This specialized service allows craft and industrial brewers to rent kegs on a short-term basis to supply tap beer to bars and venues, with the provider handling the return logistics.
Following a comprehensive Phase 2 assessment, the ACCC concluded that allowing MicroStar to acquire Konvoy’s assets would effectively create a national monopoly, leading to a substantial lessening of competition. ACCC Commissioner Dr Philip Williams warned that removing the only competing provider would leave MicroStar free to raise rental prices and degrade service quality, impacting independent craft brewers in particular.
While brewers theoretically have the option to purchase and manage their own keg fleets, the regulator determined that self-supply is not a commercially viable alternative. Managing private kegs becomes especially cost-prohibitive when small breweries must collect empty barrels from venues located far from their facilities. The watchdog also found a low probability of a new market entrant emerging swiftly enough to constrain MicroStar’s market power post-acquisition.
Although Konvoy has been in receivership and voluntary administration since March 2025 with its assets facing potential liquidation, the ACCC noted that a real prospect remains for an alternative buyer to step in and operate the business under new ownership.
MicroStar entered the Australian market in 2021 by purchasing Kegstar from Brambles. It initially sought informal clearance for the Konvoy asset purchase in mid-2025, which the ACCC opposed later that year before issuing its final decision to block the deal under Australia’s formal merger review process.
