She is a well-known advocate for member owned businesses and commissioned the first national mapping reports for the mutual sector in Australia. Her advocacy work resulted in the Australian Government minting a coin and producing a stamp series commemorating the International Year of Cooperatives in 2012.

Melina was also successful in advocating for a Federal Government inquiry into the co-operative and mutual business sector, which handed down 17 ground-breaking reforms in 2016. This was followed by Scott Morrison (then Australian Treasurer) ordering an independent inquiry into access to capital issues for co-operatives and mutuals. This led to the first enabling legislation for mutuals in Australia in 18 years. Enacted in April 2019, the new laws permit mutuals to raise investment capital whilst safeguarding their mutual corporate status.
