Not a new one, but just posting so more people realise.
Dirt cheap inter-city transport between Melbourne and Canberra, and Melbourne and Adelaide. Victorian state government halved regional travel fares a couple of years ago and Canberra and Adelaide are included as regional Victoria for… reasons.
Highlights include no SkyBus / airport security / phones in flight mode / baggage scales / sniffer dogs / price hikes during school hols.
Also these fares include free suburban public transport in Melbourne to get to/from Southern Cross, no need to involve your Myki.
Still not cheap enough to entice me to Canberra.
