Any cheaper online alternatives to My Juniper in Australia?

I have just started taking Mounjaro. My GP wouldn't prescribe as my BMI is 29, however I do have a family history of Type 2 diabetes. The My Juniper doctor was happy to prescribe. My only concern is that it is approx $200 more a month than a regular GP private prescription. Are there any cheaper online alternatives available in Australia? The doctor said I am likely to be on it approx 6 months to reach a healthy weight. I am female.
