Following its application and presentation a week ago, the PDFNL Board decided not to accept Coly’s application to enter under the league’s current structure.
According to a league statement on Thursday, this was due to geographical factors with Coly outside the league's existing catchment area.
Travel distances would have increase beyond those currently experienced by some of the league's furthest-travelling clubs.
However, the PDFNL has not ruled out the possibility of Coly joining the league in the future.
The league believes there may be opportunities under future competition arrangements for Coleambally to become a member.
They are keen to explore these possibilities and look forward to maintaining ongoing communication with the club.
For now, the PDFNL’s structure in the 2027 season will be two eight-team divisions - North West and South East.
The Blues senior football and netball teams have been part of the Farrer League since 2007 while the junior teams compete in the separate South West juniors competition which has its own fixtures.
Coleambally Football Netball Club president Danny Graham said the club was disappointed by the outcome, but would continue to try and have all football and netball grades play at the same location on the same day.
“The reasons cited for the refusal were related to distance and travel, as we were informed our presentation to clubs and the board was exceptional.
“We may have overestimated the Picola League's appetite for expansion at this stage, but we were led to believe there would be no barriers to our application when the decision to investigate applying was made.
“We do not regret trying to ensure the sustainability of the club.
“We still feel the community football/netball model will best serve us in the future and will be trying to maintain same day football/netball as much as possible.”
