Võ Anh Tuấn, Thank you for the comment. Sorry I missed your comment. How to identify the gender in this species? Ovipositor is not visible due to its long tail. Based on the tail, can we identify? I tried to google and found below pic:
I believe top one is male with shorter tail and below is female with longer tail.
mauna Kunzah, Thanks for the comment! Yes it's Orb Weaver. Many genera under that have the same pattern. :) I tried to google and got few details.
Check text "leaf-shaped pattern on their fat, roughly triangular ..." in
the page https://australian.museum/learn/animals/... match is
Tetragnathidae; Unidentified Leucauginae This spider is a very small juvenile. I think it belongs to either the Genus Lecauge or the Genus Opadometa. Its web was slanted as opposed to vertcal or horozontal and the spider was orientated head down towards the ground with the underside facing upwards. All of this seems to indicate a juvenile Lecauge sp., but there is a problem. Wikipedia states that spiders of the lecauge Genus have two rows of long, slender curved hairs on the Femurs of leg 4. My specimen appears to have slender curved hairs (not noticeably long) on the femur, tibia and metatarsus of all legs, 1,2, 3 & 4. Is this because it is a junior and will change as it grows more mature or because it is not a Lecauge, but possibly an Opadometa? I simply don't know. So "Unidentified Lecauginae" it is for now.
