Robbie passed Niall Quinn's previous mark of 21 goals with a double against the Faroe Islands in the Republic's last outing last month.
That took him to 23 goals in 56 caps - all at the age of just 24.
He'll now look to add to that tally when Ireland take on Croatia at Lansdowne Road tonight.
Robbie's coach at Spurs and Ireland's assistant boss Chris sees it as just the start.
"It was only a matter of time with Robbie and to do it at such a young age, he's got everything in front of him," said Chris.
"On the international stage, we're looking for him to keep banging the goals in way into the future.
"We have competition for places with Ireland but at the moment, if Robbie's fit, he'll play and that means he has a great opportunity to score a lot more goals."
Chris Hughton believes there is plenty more to come on the international stage from Ireland's new record goalscorer Robbie Keane.
