Attempts to salvage the Albury race meeting have been abandoned with the smoke haze from bushfires at unacceptable levels.
Racing NSW stewards confirmed Monday's meeting had been postponed because of poor air quality and visibility concerns.
Originally scheduled for Friday, the meeting was moved to Monday because of the haze.
Racing will take place at Gunnedah on Monday while Tuesday's Mudgee meeting will also be a fund raiser for the Rural Fire Services.
"We'll be raising much-needed funds for the volunteers at the Rural Fire Brigade who have all been doing it so tough in the past few weeks," MRC club secretary/manager Colleen Walker said.
"The forecast is for 34 degrees so we will have a misting system operating to keep the horses cool."
