I was hearing Blackheath base being called up on 162.3625 with reports of checking camp sites & toilets. A helicopter also came up on channel to report in.
My scanner did not pickup any subtone but what I did hear was the normal chirp of a MPT trunking channel.
This frequency is on my list & recorded in the ACMA as being licensed to St Johns Ambulance in certain sites around sydney as well as NSW wide.
It is also not listed in the Post above as a NPWS frequency but comes very close to their frequency range.
Can anyone explain?

NPWS at Narrow Neck (Katoomba) is slightly below that frequency on 162.3500 241.8
I dont pick it up well (i have a lot of local buildings in the way)

I have heard Narrow Neck on 78.775.
The only ones I have heard on VHF Hi frequencies are:
162.125 - st-241.8 - Wisemans Ferry
165.125 - Mulgoa
164.5625 - Mittagong
162.3125 - Kingscross

Can confirm heart beats from
163.4375 Mangrove Mtn Rpt
164.9875 Munmora Rpt

And heard Oberon base calling on
162.3000 Mt Tomah Rpt
while passing Kariong on M1 NB.

NPWS busy today with parks reaching their capacity by 9.20am.
Lot of activity on 164.5625 which seems to cover alot of the parks across Sydney's west. This frequency I have listed as being broadcast from Mittagong.
Other channel that came active was 162.5375 at Lane Cove NP.
