Perth NDB is set to close due to a) Perth Airport wanting to put in a road through that area and b) the NDB is not due to be replaced.
Clackline NDB - just north of Great Eastern Highway, Clackline.

What do the NDB's do?

Navigation on 200-400+ kHz. They transmit a 2 or 3 letter code (eg Albany ABA, Pearce RAAF PE) for pilots to use triangulation to determine their direction. Some, like Peace, carry terminal information. (ATIS)

its a Basic Navigational Aid (usually has a range of around 75nm), which pilots can use to track to a certain area, or airport.

Using my late father's TS-430S and a longwire antenna (approx 20m long) I have heard NDBs from as far north as Hong Kong, west to Ondangwa (Namibia) and east to Hao Atoll in French Polynesia.

in an aircraft, around 75 is the limit
some are stronger, some arent

Most have greater OW (Over Water) range though - for obvious reasons...

I have a photo of the old PH beacon (400kHz) when it was located on the south of the Swan River. I haven't got the newer one (methinks it used to be GFD on 272?) yet...

Currently PH does not have a NBD of its own how ever North of runway 21, looks like a little bit to the north side of the Swan River is CVM NBD
and to the North east roughly 9 DME of PH VOR is PRL NBD

While driving to work, i was thinking,
none of the class C airports (sydney, brisbane, melbourne, adelaide, perth, darwin) Have NBD's assigned to their airport designator
How ever, in the Melbourne area there is EPP (epping) on Finals rwy 27 and BOL (bolinda) on finals 16,
Sydney has GLF (glenfeild) and COR (cordo)

Not true - there are some Class C aerodromes that do have their own NDB. Cairns, Adelaide Canberra, Gold Coast - the list keeps going - anyway....
With regards to the range - 75nm - where did you get that range from ... ??
Nafenn - It all depends on the alt of the aircraft and the power of the transmitter - also depends on time of day/night. Sounds like a little knowledge is dangerous - especially with a student pilots licence - as you should know - you have not truly learnt about Navaids as yet.
It is good to have a conversation about aviation navaids and aviation in general - but i think if we provide correct information to people out there - that dont have an aviation background - then they can be correctly informed.
Just a thought - i will probably get burnt here - however the correct information should be known.
