We ordered Pfizer and AstraZenica vaccines but due to the rare blood clot issues in some younger people with AstraZenica, the government restricted that to over 50s.

Then when they realised that we didn't have enough Pfizer being made they tried to say that people under 50 can get it after consulting their doctor but by then they'd scared off lots of people. Pfizer is also harder to administer as it needs special refrigeration equipment.

A lot of people are also hesitant to getting the vaccine, perhaps because until recently most states apart from Victoria hadn't experienced large numbers of cases, deaths or lengthy lockdowns. That's started to change with the spread of the delta variant and more lockdowns etc.
