I assume you have Australian teaching qualification. It isn't automatically recognised in UK, and to gain qualified teacher status (QTS), you have to go on overseas trained teachers programme (OTTP) by working as unqualified teacher in a school and being supported for OTTP, mainly by having your lessons observed and creating a portfolio of evidence to show you meet required standards. Now the problem for you is that since there is a large surplus of primary teachers, very few schools offer you a post that enables you to go on OTTP, and there is little demand for unqualified teachers because of a glut of qualified staff with latest UK experience of national curriculum and various strategies. Some supply work may be available, but as unqualified teacher your pay will be a third less, and the work you get is too unpredictable as a source of steady income. Alternatively you can do a one-year PGCE to gain QTS, but the fees are high (around £12k for overseas students - even though you are British you haven't lived for 3 years in UK before starting) and you still have to serve a year's induction, and induction posts are as rare as hen's teeth.I'd contact agencies, schools wouldn't look at your CV unless you were applying for an advertised post. But now until about the end of May is the time to be looking on TES and The Guardian sites. If local councils use a specific agency for cover work it should say on the council web site. Many in the NW use protocol.
