I been auditing which P25 repeaters are still working on the 70cm band here, looks like 7 are now gone.
as of 3rd May 2022,
Operational :
VK2RMB Terrey Hills but is standalone, waiting to be configured and linked to P25 network
VK2RNS Asquith, currently standalone, as it not linked due to recent lightning strike
VK2RWK Kurrajong, standalone
VK2ROT Paddington, standalone
VK2RCG Sydney city (GPT) - linked into P25 network
VK2RHP Horsley Park, linked into P25 network
VK2RGN Goulburn - not sure if linked
Non-operational or redeployed :
VK2RWI Dural - now a VK-DMR rptr
VK2RHT Chatswood - now a VK-DMR rptr
VK2RAG Somersby - gone maybe redeployed
VK2RHR High Range - failed, getting fixed
VK2RCF Carlingford - gone
VK2RLE Heathcote - nothing
VK2RWS Berowra - gone
and possibly a P25 repeater for central west NSW (Bathurst-Orange region) being configured.
Talkgroups for these linked ones are typically TG10700 or TG10400
