A dedicated Small Business Act will seek to provide a single definition for a small business under law and guarantee owner operators are listened to in the writing of new laws under a Coalition government, Tim Wilson has revealed.

The Shadow Treasurer is expected to bring the Liberal Party back to basics on Wednesday when he announces the Stand with Small campaign at the National Press Club in Canberra.

Mr Wilson is expected to tell the nation’s business and political elite a future Coalition government would consult on the Act, which would provide a single definition in all commonwealth law for what defines a small business.

Consultation would also take place on a “right to be paid”, which Mr Wilson will say would set legal maximum payment terms to small business from government and big business.
