Seems like Bendigo is going to have regular flights to Sydney. Beats driving over to Tullamarine and back. Decent price for flights but given they are the only airline flying the route expect the price to go up after the sale. Fares include checked bags and seat selection (can either pick window or aisle).

From The Bendigo Advertiser:

TICKETS are now on sale for Qantas flights between Sydney and Bendigo. From March 31, 2019, QantasLink will operate flights six days a week with its 50-seat Q300 turboprop aircraft, and daily during the peak summer season. The first flight will leave from Sydney on March 31, 2019, and touch down in Bendigo in the evening.

Bendigo will have its first flight to Sydney on April 1. QantasLink will offer special fares of $129 one-way between Bendigo and Sydney, for travel from March 31 to October 26, 2019. The sale ends December 17, 2018.

Flights take from an hour and 50 minutes to two hours.
