She shot the southerners into fourth place overall in the championships, a much improved performance of 10th the year before. After Netball New Zealand announced plans for a new semi-professional franchise competition for 1998 season to replace the old provincial champs, the new Invercargill based franchise the Southern Sting retained Wilkins services along with Bernice Mene for the season. During the season Wilkins had scored 38 out of 51 goals against Otago Rebels but eventually lost the championship 57 to 51. She continued to play in the South for the Southern Sting till 2006, when she was called into the Suns basketball team in the AmericanWNBA basketball competition.

Wilkins did not play in the first season due to pregnancy, but continued with the Southern Steel as an assistant coach. She returned to the playing lineup for the 2009 season, where the Steel improved on their 2008 standing to reach the finals stage; the Steel were eventually defeated by the Adelaide Thunderbirds in the semi-finals.
