A tip from member Tim Jones:
The international Interstellar Award for Speculative Poetry is open to all forms of poetry, from contemporary/free verse to traditional verse. ‘Speculative’ is here defined as science fiction and fantasy, all sub-genres such as space opera, hard SF, soft SF, paranormal, steampunk, new gothic, supernatural, metaphysical fantasy, magical realism, and all hybrid genres, including new ones of your own making. The only proviso is that entries contain at least an element of the speculative.
Entries must be received by 1 May, first place prize $1000, second place prize $300. More info at the website.
Note: There is an entry fee of $12 AUD and this appears to be a new market. Use your discretion.
