Been like this for years, nothing new here
Did SIN to PER once many years ago, with two little kids in tow. 01:30 arrival, with two other aircraft within minutes of each other.
Took longer to clear Perth immigration and get a taxi home than the flight took.
Joint lousy with border farce goons stomping about, chatting with each other, whilst the line snaked slowly towards the three open counters.
I actually asked (nicely) one of the buffoons to fetch chairs for an elderly couple who were struggling with standing for so long, only to get the response "Not my job mate"...
Beggars belief.
