The government has set up a program called the 'enhanced primary care plan'. It allows you to recieve a Medicare rebate for up to 5 allied health sessions (speech pathology, occupational therapy, physio, etc) per year. The rebate is roughly 50 bucks. Technically it is supposed to be for children who require multiple services however I have seen it been given to children who just need one service. It is organised through your GP so it's worth asking them about it, if they won't don't it it's worth trying another GP.
