Thanks Kevin - that might help it get here faster.
I am not too worried, it will probably take another 10 day based on the previous book. 3 to 4 days to get from London to leaving the UK and then only a day or two to get here then another 4 to 5 days to get the last 300km after clearing Customs. To me it seems all the couriers blame Customs for the delays but generally things I order like books get though Customs within an hour or two of landing.
Amazon Australia are amazing, order by about midday and it arrives the next day. Each item shows on their website if it will get to your location by the next day or has passed the cut off. No idea how they get their couriers to be so organised when a letter within the same city can take a week.
I expect a lot of lorry drivers are sleeping in the back of their truck cab, we had a very nasty accident a few weeks ago, I think a sleepy truck driver pulled into a truck stop for a rest and ran into a few other trucks carrying flammable liquid and the whole lot went up, luckily no-one was hurt but the main highway was closed for a couple of days.
