Crown casino's bid for an increased stake in rival Echo Entertainment has been approved by Queensland's gaming authority.
The approval on Friday by the Queensland Office of Liquor and Gaming Regulation allows Crown to lift its voting stake to above 10 per cent and follows similar approvals by NSW last week.
The NSW Liquor and Gaming Authority(ILGA) capped Crown's share in Echo at 23 per cent.
"The approvals from the Queensland Attorney General and the Queensland Governor in Council (Queensland approvals) permit Crown to have voting power in Echo above 10 per cent but not to exceed an approved cap of 24.99 per cent," Crown said in a statement late on Friday.
Crown early last year included the 25 per cent limit in its application to the ILGA and the Queensland government as part of its plan to push for an increase in its stake in Echo.
However, Echo's constitution restricts an entity's voting power to a maximum of 10 per cent unless the written consent of the regulator in NSW and the Queensland government is obtained.
Malaysian gambling group Genting holds a stake of about 9.88 per cent in Echo and has also applied to regulators to lift its stake above 10 per cent.
Echo operates The Star casino in Sydney, the Treasury casino in Brisbane, Jupiters Townsville and Jupiters Gold Coast.
Crown operates the Crown casino and Melbourne and the Burswood casino in Perth.
