Simplex

FM

On VHF and UHF, not all frequencies are available for use on simplex. The RAC band plans specifies these channels for simplex use:

Column 1	Column 2	Column 3
For 2m:	146.415, 146.430, 146.445, 146.460, 146.475, 146.490, 146.505, 146.520†, 146.535, 146.550, 146.565, 146.580, 146.595	15 kHz between each channel.
For 2m:	147.420, 147.450, 147.480, 147.510, 147.540, 147.570	30 kHz between each channel.
For 70cm:	446.000†, 446.025, 446.050, 446.075, 446.100, 446.125, 446.150, 446.175	25 kHz between each channel.

†: National calling frequencies.

Or more succinctly:

Column 1	Column 2	Column 3
2m	146.415 ‒ 146.595	Δ = 15 kHz
2m	147.420 ‒ 147.570	Δ = 30 kHz
70cm	446.000 ‒ 446.175	Δ = 25 kHz

Digital

Note that on 2m, there are digital channels interwoven between some of the FM channels:

Column 1	Column 2	Column 3
2m digital	147.435, 147.465, 147.495, 147.525, 147.555, 147.585	30 kHz between each channel.

Coordination

These simplex frequencies are most often used for direct communication. However, they can also be used to link a radio to another piece of equipment (crossband, hotspot, etc).

Here are some simplex frequencies used by local hams on the Sunshine Coast.
