Robert Christgau of The Village Voice wrote: "every once in a while in this business you catch yourself thinking that teenagers don't know dick. These Aussie adolescents admire Nirvana and Pearl Jam, which is cute, and sound like Pearl Jam, which is natural—almost exactly like Pearl Jam except no good, which is useless." Chuck Eddy of Entertainment Weekly wrote: "the songs on Frogstomp almost all start out like dreary Metallica ballads and build toward gloomy, by-the-numbers grunge." David Fricke of Rolling Stone, on the other hand, wrote: "Truly shameless wanna-be's [sic] like Bush should be so lucky to have the hard smarts that Silverchair – particularly the band's main writers, singer-guitarist Daniel Johns and drummer Ben Gillies – show on such Frogstomp-ers as 'Pure Massacre' and 'Israel's Son'. When these guys turn 18, they'll really be dangerous."
