 Based on accreditation levels since 1983, it also equates to a 700,000 sales milestone.However, because ARIA was only formed in 1983 and record companies have not reported complete record sales records to them, sales are an estimation only and in the case of 1970's albums like "Hot August Night", the conservative estimates may be falling short.In 1996, MCA Managing Director Paul Krige estimated that cumulative sales of "Hot August Night" in Australia have exceeded one million units.
