Based on my experience, my recommendation is do not buy insurance with Bingle.
The biggest issue is the lack of proper customer support. There are no physical centres, no proper online support, and although there is a 1300 number, getting through can take a very long time.
When I actually needed help with a claim, I was repeatedly transferred between departments, had to explain the same situation multiple times, and different teams seemed to have different information. There was no clear ownership of the issue.
Even getting a straightforward answer about my claim and replacement car became extremely difficult and took hours of phone calls.
If you are considering Bingle, think carefully. Insurance is something you need when things go wrong, and in my experience, getting help when things went wrong was the biggest problem.
My personal recommendation is to avoid Bingle and consider an insurer with accessible customer support and a clear claims process.

All the Suncorp backed insurance companies — Bingle, AAMI, GIO, etc. are all the same. There may be one or two brands that are good (and you pay through the nose).
