This means no ADSB "in" in Australia with this unit.. Can anyone confirm this?
From the Garmin website it appears that the GTX345 is "dual link" meaning it will pick up traffic on 1090.

Dual-link Completes the Picture
The GTX 345 ADS-B receiver is a dual-link system. So, it can receive on both frequencies (978 MHz and 1090 MHz) authorized for ADS-B operations in the U.S. Not only does this provide the most complete traffic picture from aircraft transmitting on either frequency, but it also enhances your aircraft’s ability to access ADS-B transmissions and services from virtually anywhere. When integrating an active traffic system with the GTX 345, ADS-B traffic and active traffic targets are merged on the display to give pilots a truly comprehensive traffic picture.
