Online lottery betting operator Lottoland appears to be making major moves to bolster its Australian market presence.

On Thursday, the Australian Financial Review’s Street Talk column reported that a mystery buyer had purchased 2.25m shares in lottery re-seller Jumbo Interactive after the market closed on Wednesday. The shares, which represent 5.1% of Jumbo’s issued equity, changed hands at a 28% premium to their current stock price.

Under Australian Stock Exchange rules, the size of the purchase requires the buyer to be identified via a substantial shareholder notice, so all will be known within a few days. But the AFR claimed that Lottoland was the purchaser, fulfilling the company’s long-held ambitions of acquiring a piece (and possibly much more) of Jumbo’s action.

Jumbo operates the OzLotteries website under license from Tatts Group, Australia’s dominant lottery operator. Jumbo used to run a German lottery business but shut the loss-making operation down last November based on its view that the market conditions didn’t favor the reselling model. (This view isn’t shared by Lottoland, which recently declared its intentions to launch a German-facing site.)
