Season 4 is to date the only season where none of the main characters died.
Writer and executive producer Evan Katz’s affection for The Go-Betweens (an Australian indie-rock band) led to the naming of McLennen-Forster as the military defence contractor featured in season 4. The name merges the surnames of the band’s co-founding members and singer-songwriters; Grant McLennan and Robert Forster.
