Jeffress followed up a steady opening round of 71 with a seven under par 65 in today's second round to lead by two over Andrew Kelly, Luke Henwood and first round leader Ed Stedman.
At eight under the card for the opening two rounds, Jeffress will be hoping to keep the field at bay over the closing 36 holes in order to win one of two, all expenses paid Qualifying School Trips to an International Qualifying School of his choice.
With many professionals never having an opportunity to head overseas, Jeffress was appreciative of the Australian Jeep Tour and what it has achieved in its inaugural year.
"Everyone playing this week is trying to better themselves and work their way onto an International Tour. Unfortunately for many of the guys playing domestically it is just too much of an expense to be able to head to an overseas qualifying school. It is just great for us professionals to have such an internationally acclaimed company like Jeep supporting professional golf in Australia and I really hope the players that win these opportunities do Jeep proud."
Although there is much hype around the professional scores, the 4 Ball team's event is proving to be close affair. With another trip to an international qualifying school on offer for the winning professional, both professionals and amateurs will need to keep their nerves in cheque if they are to walk away with the spoils on Sunday afternoon.
Jeffress has combined well with amateur partner Paul Elliot to also lead the team's event. With a nett total of 116 for the first two rounds, Jeffress and Elliot lead by six shots over Euan Walters and Australian football star Harry Kewell, while Andrew Kelly and Scott McGregor are one further shot back in third.
With the perfect weather conditions set to continue over the final two rounds, low scores are again going to be on the cards over the weekend. Round three gets underway tomorrow morning at 8am, with the inaugural Jeep Tour champion to be crowned on Sunday afternoon.
