It means that the pay television rights for Nemesis and nu Trek 1, either were no longer exclusive to whatever pay TV channel that had them under licence, or said license came up for renewal and Netflix AUS won over the local competition.
If the series aren't locked down by another local network/basic cable/pay TV service, NF AUS can put in a bid to secure them. However CBS-Paramount's international syndication division will have to want to sell it to them. Except for TNG, none of the other live action Trek shows have been sold to any of Netflix's non US divisions.
