Talking specifically about radio gear, if the total value of the item including shipping is less than $A1000, no customs duty apply.
How To Import
For items over $A1000 total value customs requirements apply including specifics regarding receivers and transmitters, but I will not muddy the water here.
You may incur a GST of 10%. The seller may collect it, or if they use a freight company they may charge it.
My experience has been that items below a total value of $A1000 if sent by post (and not an ebay type purchase), they have come straight through and nothing has been charged.
(E&OE, YMMV etc.)

Quote:For most goods with a value of AUD1,000 or less there are no duties, taxes or charges to pay. You must pay duties and taxes on some goods (like tobacco, tobacco products or alcoholic beverages) regardless of their value.
