It was a firey match, with both teams playing in a physical manner, which left Adelaide United coach Josep Gombeau furious at Newcastle's style, conveniently ignoring his side gave just as well as they got.
For Adelaide, it's another solid defensive performance after struggling for much of the season with defense they have now recorded three straight clean sheets.
Adelaide nearly took the lead just eight minutes in as Isaias hit a corner that curled in and caught the breeze, catching out Mark Birighitti, but going wide of post.
The hosts were the better side as they managed to control possession with their flowing passing game, while also being solid defensively, their dominance showing as Newcastle couldn't get a single shot on target.
In the 20th minute Sergio Cirio should have made it 1-0 as he got free but was denied when Jacob Pepper made a great run back to slide in and deny the Spaniard.
In the 26th minute Adelaide United were able to get the goal that they so richly deserved as Jeronimo sent in a cross that Mark Birighitti cut off for the rebound to fall for Steven Lustica, that was blocked by Josh Mitchell but fell for Bruce Djite, left unmarked, who easily poked home in to an empty net.
It could have very quickly been 2-0 as Cirio's speed set up Jeronimo who hit a nice curling effort that was well saved by Birighitti.
That saw the Jets start to get frustrated and there could have been red shown as Taylor Regan took out Marcelo Carrusca with a nasty sliding challenge, getting away with a yellow card, the first of many issued in a run of cards that was split by the half time whistle.
Gombeau could well have also landed himself in trouble at the half time break as he had a very heated discussion with referee Chris Beath, who remained cool and kept from dismissing Gombeau.
There were four yellows in the final ten minutes of the half as they ramped up the physicality of the match, split between both teams.
In the 59th minute Adelaide could have had a red card of their own after another nasty challenge with a vicious studs-up challenge on Ruben Zadkovic, but got away with a yellow, but the Reds escaped as Zadkovic sent the free-kick high.
The Jets took justice on Carrusca in to their own hands as Nathan Burns went studs up on Carrusca, resulting in Carrusca having to leave a field in an injury while Osama Malik left, complaining of grogginess after a head clash.
It took until the 62nd minute for the Jets to have their first shot on target as Adam Taggart found space who was able to get a shot away but was denied by a Eugene Galekovic save.
With two minutes to play Jake Barker-Daish nearly made it two as his shot came off both posts allowing Birighitti to recover and make the save.
