The association yesterday released results of its latest annual referendum, conducted online between Tuesday and Thursday.
Of 1340 students who voted, 90% supported the OUSA adopting a policy in favour of ''guaranteed student representation on university governance boards and committees''.
The policy also required the OUSA to ''actively'' oppose the Education Amendment Bill (No2), which is still being considered by Parliament.
The proposed legislation would reduce the overall size of university councils, and still allow student representation on councils, but this would not be guaranteed.
Student voters also strongly backed the OUSA adopting a policy of supporting the return to a universal student allowance, with 78% of 1369 votes cast in favour.
Even stronger support went to the idea of the OUSA supporting the removal of GST on fruit and vegetables, with 86% of 1379 votes cast in favour.
A further 71% of the 1379 students voting suggested that the OUSA executive investigate the establishment of a student bar.
A total of 52% of 1358 referendum participants voted against the proposition that the OUSA support the legalisation of marijuana.
A further 48% of students favoured it adopting that policy, after the ban on all existing synthetic cannabis products.
OUSA president Ruby Sycamore-Smith said it would campaign in the coming election in favour of guaranteed student representation on university councils, for universal student allowances, and also for the removal of GST from fruit and vegetables.
Students wanted their voices heard, and students spoke up for ''education quality as well as efficient and effective universities'', she said.
