Ok.
First you want to have an introduction discussing the growth of the aus economy, and how it is generally acknowledged that australia seeks to foster and protect its domestic industries from outside competition.
then discuss why we employ the policies > to protect new and emerging industries that have not had the opportunity to sufficiently develop productivity efficiency + market share + very briefly add in the other reasons
then discuss the forms protection take
then go into how these benefit domestic producers at the expense of importers.
discuss the various effects of the protectionist policies, perhaps add in a tariff diagram showing this.
give examples throughout, e.g. strong protection in the E.U has decreased exports of agricultural goods as they protect their ag industries very heavily
and yeah just go on from there, that's off the top of my head, i wrote a 20/20 essay on the question "analyse the impact of protectionist policies on the domestic and global economies" if you want it.
