South Rotary is calling on local businesses, sporting clubs, and community groups to commit to this year's Christmas Pageant for the city's children.
Nominations are now open for the Pageant, which is run by the Rotary Club of Broken Hill South and Broken Hill City Council.
Mr Cullenward said he would dearly love to see this year's event get sufficient early nominations to ensure the event won't be threatened with cancellation.
"It seems every year the nominations are slow to come in, and people only get a move on once it looks like the event may not go ahead," he said.
"It must be somewhat disheartening for kids and families to see the pageant in danger of cancellation year after year, so it's something we'd really like to avoid this time around."
Mr Cullenward said early nominations would also help in the overall organisation of the event.
"I know in Broken Hill we tend to leave things until the last minute, but this year we'd love to see everyone lodge their nomination early so we can get stuck into planning, rather than having to do everything at the eleventh hour," he said.
"It doesn't matter if you don't have your float organised yet, just get your nomination in early, and work out the details in the months to come."
As always, the Pageant will be complemented by an after-party in Sturt Park, which will feature food and drink stalls and children's entertainment and activities.
Those wishing to nominate a float for the pageant or reserve a stall at the after-party can do so online, with nominations to close on 23 November.
The pageant will begin at 6pm on 1 December 2018, with the after-party in Sturt Park to follow at 6.30pm.
