Hi Nathan,
is it possible for you to either repost the article or provide a link to the entire contents please.
AFR kick me out as I am not a subscriber.
There must be some bits missing from it as just 600m is not enough according to all the figures we have to choose from.
I suspect there was a 300m from half DBCT and another 600m from rights that should be in that article.
cheers
