Oz Day shows a rainbow of diversity

Bypass tunnel rusting away Ken Sapwell

A road tunnel built as part of the $540 million Tugun bypass project is showing alarming signs of acid corrosion just seven months after being opened. The walls of the 333-metre-long tunnel contain visual evidence of iron staining and leakage which some fear could undermine the tunnel’s longterm integrity and leave NSW taxpayers with a multi-million dollar repair bill. Tweed’s bypass watchdog and researcher, Lindy Smith, says high levels of sulphuric acid eating into the tunnel’s iron framework is part of a chemical cocktail also posing a major environmental threat to the Cobaki broadwater. Tweed Australia Day ambassador Donnie Sutherland and 15-year-old Community Service Award winner Caitlin McGibbon-Goode put on their brightest happy faces for The Echo photographer after Caitlin was presented with her community service award by Donnie at Uki Sports Club on Monday. In the background Tweed Australia Day committee chairman Don Beck gets ready to announce the next award.

Thirty-one Tweed residents originating from all corners of the world became some of the country’s newest citizens after a naturalisation ceremony at Uki on Australia Day. The new Australians, young and old, came from the Netherlands, United Kingdom, United States, South Africa, Thailand, New Zealand, the Philippines, Russia, India, Canada and Cyprus. Tweed mayor Joan van Lieshout, who conducted the citizenship ceremony, wished the newest Australians well after pledging their allegiance to their newly-adopted country and they were all congratulated afterwards by family and friends. Cr van Lieshout noted the multicultural backgrounds of each, say-

ing Australians ‘respected diversity’ and that the country’s heritage was made richer by people from other countries. ‘We are all migrants,’ she declared. A crowd of well over 400 people, including local political representatives,

‘Battery acid’

Sutherland, OAM, summed up what he thought it meant to be an Aussie when he kicked off his address by asking the crowd to turn to the person next to them and ‘say g’day’, a gesture which won instant rapport with the crowd.

‘We are all migrants.’ braved the sporadic rain to attend the official Tweed Shire Council Australia Day celebrations at the Uki Sports Club grounds, while hundreds more attended other celebrations in towns and villages throughout the shire on Monday.

The former host of the long-running TV music show Sounds said Australia Day ‘celebrates the diversity of our rich country’ and was a time when ‘our national spirit comes to mind’, especially the spirit of volunteerism in all its many forms, from emergency services to Olympic Games. continued on page 2

Ms Smith says the results of test monitoring she obtained from the NSW government reveal the tunnel is sitting in a bath of acid-contaminated groundwater comparable in strength to battery acid. [Water with a Ph level of seven is considered neutral. A Ph level of six is 10 times more acidic, a Ph level of five is 100 times more acidic and so on until a Ph level of one is 100,000 times more acidic. Monitoring of bypass runoff shows levels between one and two at some points.] The high sulphuric acid levels arising from disturbance of acid-sulphate soils during construction have also unleashed huge loads of iron precipitate containing arsenic and zinc which are released by natural processes when flushed into estuaries. She says tests show levels of these elements along the shores of the

broadwater already exceed those at two other acid-sulphate hot-spots in Australia now subject to highly expensive remediation programs. They are at East Trinity in Cairns and Sterling in Western Australia where the scale of the environmental hazard was considered big enough to pose a public health risk and require ongoing management.

Longterm investigation Her findings have prompted Tweed Shire Council to support an independent investigation into the longterm risks created by bypass runoff to the local marine and estuarine environment. The council this week authorised its river committee head, Tom Alletson, and acid-sulphate soil experts Robert Quirk and Southern Cross University’s Professor Leigh Sullivan to design a process to monitor water discharges into the broadwater and its longterm ecological impacts. Ms Smith, who’s been studying the results of tests provided by the Queensland Department of Main Roads to the NSW government since work began three years ago, has applauded council’s decision. ‘The tests confirm that the NSW government’s initial opposition to the project was not misplaced,’ said Ms Smith. (See story page 2.) ‘There are huge discrepancies between the figures in Queensland Main Roads’ final construction compliance report (CCR) and those provided from various monitoring points,’ she says. ‘In most cases the CCR’s figures underplay the levels of acid sulphates and iron precipitates and I see this as an effort by Queensland Main Roads continued on page 2
