During the 2001 pre season Souths held the 'Legends of League' Oztag competition at Redfern Oval featuring all the traditional clubs of the NSWRL and someone decided that Canterbury had the right to the royal blue and white colour combination and Newtown were allocated an unfamiliar navy blue and white colour scheme. All the jerseys for the competition were made by ISC Sports and had the same design, essentially a white jersey with stripes/hoops in the middle and at the top of the design. This is signed by the Jets legends who played on the day. 
The jersey at the bottom is a players version from 2001 with the rare sponsors on the back and sleeve. Haven't ever seen another one being worn at games or even for sale.
