Many of the Level 2 supplier of poles and connection reckon that standard gal poles typically only last about fifteen years before corrosion at ground level renders them unsafe, whereas they say hardwood is more like 30-40 years in similar conditions.
Fifteen years sounds kind of short to me. Aside from catastrophic failures (external events), I haven't seen one die yet. Has anyone here actually seen a gal private pole that has failed from ground level corrosion or is at imminent risk of failing?

My brother is a L2 Supplier. He often changes wood for gal poles.
I think it's rubbish. The poles are like 5 or 6mm thick. He sprays them with something when he cuts into one - probably a gal paint of sorts to protect the cut.
The only way I can see one failing is if it somehow fills with water and it rots out from the inside but that will take quite a while considering the thickness of the steel.
I see you are in Sydney. Let me know if you need his number
