Back to the Future, page-8

Most won't be aware of this, however, the ATO issued issued tax ruling TR 2008/1, which specifically outlaws arrangements where “...in substance there is no significant change in the taxpayer’s economic exposure to, or interest in, the asset, or where that exposure or interest may be reinstated by the taxpayer”. In other words, the ATO prevents investors from selling a stock in one financial year to take advantage of a capital loss event, only to buy that stock again in the new financial year. This is known as a “wash sale” and the ATO will disallow the loss if the sole intention of the sale was to minimise tax.

So those selling PAR (or other holdings) into FY end need to be very cautious as they may end up losing on two counts if they're entertaining re-entry. To comply with tax law as an investor (as opposed to classifying yourself as a trader) and receive the CGT discount you are effectively required to make a conviction call with a long-dated horizon.
