Following phylogenetic analysis, the species was placed in L. peronii clade group alongside L. depressus, L. tasmaniensis and L.

[4] Breeding occurs mostly after heavy rain and eggs are laid in a floating foamy mass, often attached to vegetation.

[5] Although the species population is considered 'Least Concern' under the IUCN Red List and stable, L. fletcheri threatened by habitat loss.

There is a positive relationship between flooding frequency and the breeding activity for L. fletcheri[6][7] Flooding between September and December is required to maximise breeding responses from the species, this will increase the likelihood of species persistence and diversity.

[7] Therefore, the species may be negatively affected by regulatory activities such as damming and would respond positively to environmental flow management[6]
