Of course, insurance, rates, and body corp can take a good chunk if you don't know what you are looking for. However, they are not necessarily something that should put you off buying in a particular area.
Body corp is a generally a pain anywhere, and it's no different in North Qld. In Qld, units that have more than 5 in the complex are subject to the Standard Module, which is not ideal. Too much paperwork, among other things. Plus, Body Corp managers can charge excessive and unnecessary fees, so you do need to be aware. Personally, I would rather consider units with 5 or less in the complex, which can be administered under the Small Schemes Module. This means decision-making, fees etc can be restrained.
As for insurance, you do need to do your DD. As with anywhere, don't buy in a flood prone area. Make it your business to understand how to ensure reasonable premiums. Ask local agents, and get a quote from a good local insurance broker before you buy.
