The film lacks LGBTQ+ characters or non-heteronormative identities. The central romantic arc focuses exclusively on the marital bond between the lighthouse keeper and his wife.

The narrative centers on the female protagonist's psychological agency and emotional labor. Her struggle with infertility and her decision regarding the infant drive the film's primary conflict.

Set in 1927 Australia, the cast is predominantly white. While the infant's lineage introduces tension, the film does not prioritize a diverse cast or utilize color-blind casting.

The story explores moral relativism by prioritizing personal emotional truth over legal mandates. It challenges Western legal institutions by framing the characters' choices as sympathetic necessities.

The film examines the psychological grief of infertility. While treated with depth, this functions as a plot catalyst rather than an exploration of physical or neurodivergent disabilities.
