Off topic – Identification of a flowering shrub in Torres Strait

Hi All, I?m hoping somebody might be able to point me in the right direction regarding the ID of a flowering shrub on the northern islands of Torres Strait, QLD. When flowering it is visited by both Dusky and Red-headed Honeyeaters. Most specimens are 2-3 m tall, woody (not brittle) with numerous short, sharp, slightly curved spines that project off the branchlets. The flowers are small white, rather furry/fluffy on the upper surface of the petal. Each flower appears to have either four or five petals. Flowering has been observed in November when unripe green fruits are also present. On Boigu Island it grows in a disturbed area immediately adjacent to mangroves. The area is probably inundated by extreme spring tides so the shrub also appears to be salt tolerant. A link to a couple of pictures (including a Red-headed Honeyeater) is here. http://upload.pbase.com/edit_gallery/wildlifeimages/unknown_shrub
