Are you sure? How about a reference? On the BOM website it says about a TAF:
Wind
The wind direction is given in degrees True, rounded to the nearest 10 degrees. A
variable wind direction is given as VRB (used when the forecasting of a mean wind
direction is not possible).
The wind speed is given in knots (KT).
The maximum wind gust is included, after the letter G, if it is expected to exceed the
mean by 10 knots or more, e.g. 28020G30KT gives a wind direction of 280° True, with
a mean speed of 20 knots, and a maximum gust of 30 knots.
