In response to points:
> Presumably the 5 watts you mention is the upper limit permitted?
Yes, a ZL LF permit allows up to 5 watts radiated power.

Some homework is needed on sunset and sunrise times, as near-antipodean
paths do not have much mutual darkness for each end of a path. In practice
ZL6QH would transmit for all hours of local darkness, and selection of
reception time(s) can be estimated at "your end".
Dates already identified for LF DX testing from ZL and VK are 1 and 15
December (Saturday night ZL time, which is +13 hours on UTC). These dates
were not selected on the basis of good sunrise and sunset times with respect
to Europe, but they could be times for a 136 kHz squirt from ZL6QH.
I have worked ZL many times on 160 metres so maybe I am in with a chance
I have suitable LF antennas for the job if it is at all possibe to make
Best times on 160 are sunset/sunrise times this might also be the
136 khz but it does not always follow on LF.
Signals on 136 khz around EU are just as good day time as well as night,
longer distances we will have to find out.
I frequently work OH1TN daytime at 589 each way over 1600 km away, his
just as good day time as night, in fact there is more noise during the
