In a letter dated October 14, Byron Bay Chamber of Commerce president Mark Ryan requested the measure be slightly relaxed.“We respectfully request that a ruling allowing regional NSW residents who have had their first vaccination and will be fully vaccinated by November 1 2021, be allowed to enter any business premises from today onwards.”Mr Ryan said in the letter this change would allow many local businesses to survive.“We are informed by our members that local businesses are in some cases down 70 per cent in sales, in comparison to last week due to the reduction in their customer base,” the letter reads. “Unless local customers can return to venues after having had at least one dose of a Covid-19 vaccine, Byron Shire businesses will not be able to continue to trade.“This allowance will assist in at least sustaining local businesses with customers until the rest of NSW is able to travel to the Byron Shire under the 80 per cent vaccinated road map rules.”The letter was addressed to NSW Premier Dominic Perrotet, and was also delivered to deputy premier Paul Toole, Health minister Brad Hazzard and MLC member Ben Franklin.Earlier this week, businesses in Byron Bay lamented the changes to the Health Order triggered a sharp decrease in trade. Travel from Sydney to the regions will still be banned from Monday, even though NSW will reach the 80 percent vaccination threshold over the weekend.Three new casesThis comes as Northern NSW recorded three new Covid-19 cases in Lismore, Grafton and Richmond Valley while one case in Coffs Harbour was removed from official records.According to the Northern Local Health District, one case was recorded in Grafton, a household contact of a previously reported case, one in Casino linked to an existing cluster, and one in Lismore under investigation, up to 8pm Wednesday.The Clarence Valley cluster remains the biggest in Northern NSW with 24 cases in the past four weeks.There have now been 92 total cases reported in NNSWLHD since the Delta outbreak began in Sydney on 16 June.The local infections are part of 406 new locally acquired cases in NSW and four deaths.A NSW Health breakdown of Covid cases in the past four weeks shows:Ballina: 9Byron Bay: 6Clarence Valley: 24 (+1)Coffs Harbour: 5 (-1)Kyogle: 16Lismore: 14 (+1)Richmond Valley: 17 (+1)Tweed: 4NSW Health on Wednesday confirmed Aldi Ballina was visited by a Covid-positive person on Friday, October 8 and anyone there between 6.30pm to 7pm should immediately get tested and isolate.
