Corals were collected over the sampling period and sex determined during the annual coral spawning event. After spawning weight and height were recorded and new corals were tagged before returning to a marked location. In addition, this dataset contains a collection of oocyte measurements of two scleractinian corals, Acropora millepora and Fungia concinna, and one alcyonacean corals Lobophytum pauciflorum to identify the onset of gametogenesis over a 13 months period, starting in January 2014 and ending in February 2015. During this period, coral tissue samples were collected once a month and samples for histology were promptly fixed for 24h in 4% formaldehyde solution. Histological sections were stained with Haematoxylin-Eosin and analysed for gonad development. Gonads were identified using a 10x magnification of a compound stereomicroscope. Only the diameter where nucleus was clearly visible was measured under appropriate magnification using the cellSens software (cellSens standard v1.8) to ensure that the full size of the oocytes was recorded. Gonads were grouped in different size classes relative to the final size of the oocytes. For A. millepora and L. pauciflorum the size groups were determined as following: Stage I oocytes (< 50 µm), Stage II oocytes (50 – 99 µm), Stage III oocytes (100 – 199 µm) and Stage 4 oocytes (> 200 µm). F. concinna oocytes were significantly smaller than Acropora and Lobophytum oocytes (p < 0.05). The size groups were therefore adjusted for this species: Stage I oocytes (< 25 µm), Stage II oocytes (25 – 49 µm), Stage III oocytes (50 – 74 µm) and Stage 4 oocytes (> 75 µm). In order to test for possible correlation of oocyte development with water temperature, data for daily average water temperatures at 6.1 m depth for the sampling period at Orpheus Island were downloaded from the AIMS data centre for relay pole 2 (https://apps.aims.gov.au/metadata/view/748ba679-92c6-4827-a46e-e7265323deb9).
