These are the five seats that will determine election. Three so far have ALP in front and 2 the Libs in front, hence why they are saying on AEC website 72 ALP, 66 LNP and 5 independents with the initial screenshot says 7 seats undecided - more around who came 2nd in those 7 - but when go through that list of 7 in fact 6 fall to LNP and 1 ALP so 72 Libs, 73 ALP and 5 independents.
Now going back to the 5 seats in this link - essentially what LNP is saying is postals will favour LNP and they will win them making the total 75 libs, 70 ALP and 5 independents. A big call - take Chislom ALP in front by 25 votes. Have fun. The postals will decide this - IMO ALP could form Government if stay on 73 - I suspect Wilkie, Bandt and McGowan will side with ALP. So all eyes on postal.
