I presume this is a binary log file for the database.
Am I able to recover to a point in time using this log file?
What I would do in SQL Server would be recover to a point in time, say a bit before the last completed transaction time the log mentions, then take a backup. Is that possible in postgres?
The log mentions this:
2017-01-27 20:36:18 AEDT LOG: last completed transaction was at log time 2017-01-24 02:08:00.023064+11
(which is moments before, or possibly as the disk filled up doing a db backup dump)

Best guess is the last WAL is not complete.
From your original post:
"Attempt 2 - startup manually and let it try recovery
I restored my file level backup and started again. "
How was the file level backup done?
