Community support has boosted Brisbane's struggling Polish Club as a critical deadline nears to repay a $150,000 loan and avert the sale of the club's Milton home.

More than $90,000 has been fundraised since the club's new management committee put out an urgent call for help three months ago, but the club still needs to raise a further $60,000 by early August.

The new committee of "Polonia", the Polish Association of Queensland, was elected in April following years of dispute between the former committee and some of its members.
