Arthur's men had to climb back from a 16-point deficit before securing the win off the back of a barnstorming second-half showing.
However, despite the comeback attempt, Arthur was left "annoyed" by his side's lacklustre opening to the game which saw the Broncos romp to a 16-0 lead.
"It was exactly what I asked them at half-time, just get back to playing our game," he said.
"A half of footy is a long time but we just needed to respect the opposition a bit more. I'm a little bit annoyed that we didn't show them enough respect early, or in the first half. I don't want us to be a team like that.
"In the last couple of years we couldn't have fought back. (The first half) was a reflection of not respecting the opposition or ourselves.
"We thought we could pass our way to (a win) instead of working hard."
While he was annoyed at his side's attitude in the first half, Arthur said he was confident that his charges could turn the game around after the main break.
"I think we had 33 per cent possession in the first half," he said.
"There was a lot of hard work to be done so we just needed even possession, we didn't need anymore, but just even possession.
"We've worked really hard in the pre-season and I saw how calm they were in the sheds at half-time.
"I spoke to our assistant coach and he said they were really calm on the field, so that was a good indication for me.
"We challenged them around lot letting the Broncos score in the first 10 minutes (of the second half)."
