Austin's 23rd goal of the season and Michael Duff's 74th-minute deflected header helped Burnley end a five-game winless streak.
Dyche opted to heap praise on the Clarets' work ethic in securing a clean sheet, as well as highlighting his team's attacking successes.
He said: "I have spoken recently about how the performance levels have been worthy of more points on the board and there were signs of another good performance. It was very pleasing.
"The clean sheet was appropriate given that we have had a couple of goals recently that have gone in against the run of play and that can be a bitter pill to swallow but they went about their business well.
"A lot has been made of Charlie scoring but behind that there are another 10 players and it is important that they are ready to do their job if he has a quiet day."
Dyche added: "I thought we came out worthy winners.
"We're one loss in seven and we are looking good value for that and if I am being greedy we are better value to have more points than that."
