Jetstar complaint: Cancellation of flight

On the 21222 I checked my flight status on line on an upcoming flight on the 250322 from Perth to Coolangatta. Flight JQ983 depart 23:35. Booking number VFLKN1.
I found the details correct. I logged out but immediately logged back in to check if I had ordered a meal, I then discovered the flight to Coolangatta was cancelled however the return flight was still valid.
The following day I telephoned Jetstar and I was informed direct flights were cancelled also the return flight on the 2422 was now cancelled. The man rebooked a flight to Coolangatta for the same date the 25222 via Melbourne and also rebooked the return flight on a day following my original which is now on the 3422.
I am very concerned about contracting Covid-19 and the thought of having a stop over in Melbourne is very worrying. I therefore looked up Qantas flights to see if I could get a direct flight to Coolangatta. To my surprise I was directed to Jetstar and found there was a direct flight to Coolangatta on the 25322 at 23:35 flight number JQ983. The very flight my booking was cancelled on and I was told there are no direct flights. I subsequently have booked a seat on this flight with Qantas booking reference number 6OYM73.
