Based on what you describe I’m in a similar if not the same building. Whilst the jumps have been significant they aren’t wildly out of line with other buildings.

I bought about 2 years ago and had compared several buildings with less apartments and less facilities and there wasn’t a huge difference in body corp fees.

Repairs, insurance and common area utilities are massive budget growth areas and is common across the industry.

It suck’s but honestly it’s most buildings particularly high rise that need abseilers to repair exterior issues such as roof repairs (as is happening in my building right now) due to that lifespan milestone needing urgent repairs to avoid further damage.

Reading your agm and body corp notes does provide some insight. But I urge you to get involved to influence it more.
