The Wales and Cardiff Blues full-back produced a flawless performance as he slotted two penalties and nine conversions in Perth.
But he insists there is plenty of room for improvement and has challenged the Lions to go up a gear in Saturday’s clash with Queensland Reds.
“I’m pretty pleased with that – I’ll take that,” said Halfpenny.
“It’s a good start but it doesn’t stop there. We will enjoy this victory, which is special, but we have to get back on the training pitch and the work will continue.
“The boys set the bar in Hong Kong and for us it was about taking it to the next level. We did that today. We were clinical; when we had opportunities we finished them. It’s about taking it to the next level again now.”
Halfpenny was in red-hot form as Wales successfully defended their RBS 6 Nations crown this year, for which he was named Player of the Championship.
And he continued to impress in another red jersey, which will have Warren Gatland purring ahead of the Test series with Australia.
Halfpenny never looked like missing and he has paid tribute to Wales and Lions kicking coach Neil Jenkins, who nailed 1090 points in a remarkable Test career.
“I continue to work on what I do day in day out and going through my routine,” added Halfpenny.
“Neil Jenkins gives me pointers and reminds me about what I am good at. I’m pretty pleased with the way I struck the ball.
“It doesn’t get much better than to have a legend of the game, someone who was the world top points scorer at one time, to give me pointers before a kick.”
