Buckingham, 23, impressed for South Australia in the most recent Sheffield Shield season, where he took 25 wickets in his first seven first-class matches at an average of 26.56 for South Australia.

His returns resulted in selection for the Australia A tour of New Zealand in April and he took 6 for 58 in his first appearance, dismissing the New Zealand A top six.

"I'm really grateful for the opportunity to represent such a proud club in Northamptonshire during my first stint in the UK." Buckingham said. "I'm thoroughly looking forward to getting stuck into it this week and to winning some four-day cricket with my new team-mates for the next few games."

Buckingham trained with Northamptonshire's squad this week ahead of their trip to Somerset and is available for the club's next three LV= Insurance County Championship fixtures.

John Sadler, Northamptonshire's head coach, said: "We're delighted to have Jordan on board. He's an exciting young prospect who's rated highly by Cricket Australia. He showed his quality for Australia A recently and we think he'll complement our bowling attack well."
