Engelaar, whose previous clubs include FC Twente, Schalke 04 and PSV, spotted Central Coast Mariners goalkeeper Liam Reddy on the edge of the box and the former Dutch international fired the ball into the net from about 70 yards.
"It was a great goal," said Heart coach John van't Schip. "It's a special moment. You can see the ball going and you think 'what's happening?' and everybody is reacting in a way that was great."
Engelaar's strike followed Wayne Rooney's contender for Goal of the Season against West Ham United in the Premier League on Saturday.
With David Beckham, who famously scored for United from the halfway line against Wimbledon in 1996, watching on, Rooney smashed a half-volley from just inside West Ham's half past stranded goalkeeper Adrian.
