I'd say this means that Austals other facilities are reaching capacity.
That or bean counters made the determination that more profit could be earned by having the work done outside WA, since a yardworker in Cebu could be paid less than one in Henderson.
Given the tone and questionable nature of the blog making the initial report, I am going to wait for Austal to make a corporate announcement that they have setup a facility in Cebu. Until Austal does that, and/or makes and announcement that they are fufilling some orders from a Philippines/Cebu facility, I would not assume that Austal is actually opening a third facility just yet.

EDIT: Additional comment.
There are basically three reasons for a manufacturer to open a new facility, especially a new facility overseas. These are;
1. Access to a new market/markets. An example of this occurring would be Austal's Mobile AL facility, which allowed Austal to participate in the USN's LCS programme.
2. Next is reduced operating costs for a new facility. This is particularly true of manufacturing facilites being setup in developing nations. The workforce/labor costs are generally significantly lower than in industrial nations in addition, many of the OS&H and environmental requirements found in industrialized nations are either significantly less or non-existant in developing nations. As long as a sufficiently skilled workforce and QA team exists on-site, a facility in a developing nation will have a lower operating cost than one in Australia, the US, or other similarly developed nations.
3. Original site has reached capacity. As a rule, this is the least likely of reasons for a company to setup an overseas production facility, simply because it is usually easier to expand a site to increase capacity. Unless of course a major expansion of capacity (doubling, tripling capacity, etc) is required.
