Away from the major population centres, the biodiversity of Australia's shallow coastal marine waters is poorly known. The Tweed-Moreton Bioregion, covering northern New South Wales and south-east Queensland, is both a focus of marine conservation (with three marine parks), and research efforts to predict the effects of climate change through species range extensions and shifts in community composition. Here we provide the first comprehensive list of shallow-water (<30 m) shelled, gastropod macro-molluscs (>5 mm) from the Solitary Islands Marine Park, compiled from a range of sources, including field collections over a 30-year period to 2017. The Cypraeidae (50 spp.), Muricidae (47 spp.) and Conidae (32 spp.) were the most speciose families, accounting for 26% of the total inventory of 500 species from 77 families. A total of 143 species are recorded at their southern limit of distribution on Australia's east coast, most being rare, tropically affiliated taxa found at offshore island sites that receive more frequent contact with the southward-flowing East Australian Current. The inventory confirms the high biodiversity of the Solitary Islands region and the importance of ongoing conservation management.

除了主要的人口中心，澳大利亚的浅海沿岸海洋生物多样性还鲜为人知。特威德-莫顿生物区覆盖新南威尔士州北部和昆士兰州东南部，既是海洋保护的重点（拥有三个海洋公园），也是通过物种范围扩展和群落组成变化来预测气候变化影响的研究工作。在这里，我们提供了来自孤独群岛海洋公园的浅水（<30 m）带壳的腹足纲大分子（> 5 mm）的第一份综合清单，该清单是根据一系列资料汇编而成的，包括30年期间的田间收集物到2017年。Cypraeidae（50 spp。），Muricidae（47 spp。）和Conidae（32 spp。）是最特异的科，占77个科的500种物种总数的26％。在澳大利亚东海岸的南部分布范围内，总共记录了143种，最罕见的是在离岛岛屿站点发现的热带附属物种，这些站点与向南流动的东澳大利亚洋流有更频繁的接触。清单证实了孤岛地区的高度生物多样性以及正在进行的保护管理的重要性。
