Plummer feels it is important that players don't go to Delhi with too many expectations as any hiccup would then be enough for their preparations to go off-track.
"I think you go into the Commonwealth Games not expecting to get a jewel in the crown," Plummer was quoted as saying by 'The Daily Telegraph'.
The October 3 to 14 Delhi Games, marred by delays in infrastructure construction, are now plagued by allegations of widescale corruption, which have resulted in suspension of three top Organising Committee officials so far.
Plummer said she doesn't expect the Games to be smooth and was preparing her team accordingly.
"I think you go in expecting some hiccups. You go in expecting the worst and if it comes out great that's fantastic," she said.
Australia have been drawn in a pool comprising Samoa, India, Jamaica, Malawi and Trinidad and Tobago in their preliminary round matches.
Reigning Commonwealth Games champions New Zealand are drawn with England, Papua New Guinea, the Cook Islands, South Africa and Barbados.
