Islands in the 1960s (Frankenberg 1967). 
Andrews (1976) was surprised at the absence of 
G. cleaveri from the Bass Strait islands and 
mainland Australia, even though at that time he 
did not know that the species possessed a marine 
juvenile stage. 
G. cleaveri was first recorded on mainland 
Australia in 1980 from the south-east side of 
Wilsons Promontory, Victoria (Jackson & 
Davies 1982). In 1983 another individual was 
recorded from the lower reaches of the Wye 
River, Otway Ranges (Koehn & O’Connor 
1990a; specimen NMV A7594, Department of 
Ichthyology, Museum of Victoria, Melbourne), 
extending the known range of the species into 
western Victoria. These two sites are referred to 
herein as sites 1 and 2 (Fig. 2, Table 1). 
Subsequently, Green (1984) reported G. cleav¬ 
eri from a drain on Flinders Island, Bass Strait 
(specimens QVM 1984/5/6, Queen Victoria 
Museum and Art Gallery, Launceston, and 
NMV A3391). This record completed a distri¬ 
bution pattern coinciding with that of other 
galaxiid species having a trans-Bassian distri¬ 
bution, namely G. brevipinnis, G. maculatus 
(Jenyns), G. truttaceus (Valenciennes) and Gal- 
axiella pusilla (Frankenberg 1967). 
It is not surprising that G. cleaveri has been 
recorded in only two of the numerous other sur¬ 
veys previously conducted to determine the dis¬ 
tribution of freshwater fish in coastal Victoria 
(see Koehn 1990, Koehn & O’Connor 1990a, 
Koehn et al. 1991). Sites sampled during those 
surveys were mostly in streams rather than in
