The Australian newspaper reported on Wednesday that listed Australian property group Charter Hall and the Wesfarmers-owned hardware chain, Bunnings, had teamed up to bid for 43 Masters sites. A source told CNBC that Costco was also part of the bid group.
Reports suggest any bid could be worth up to 1 billion Australian dollars ($770 million).
In January Woolworths said it was looking at options for Masters, including selling or winding up the underperforming business. It also said it would buy the one-third stake in Masters owned by U.S. retailer Lowe's.
Bunnings already dominates the home improvement space in Australia and recently expanded with the acquisition of the UK's HomeBase, its first push offshore.
