perhaps add "both" here instead
work to strengthen the arguments and debunk the issue,
however, unnecessary, take out they attempt to persuade the reader in different, separate ways. Campbell
almost unnecessary attacks the authorities by savagely questioning their manhood,
and change to something like "whilst simultaneously" making them look incompetent through the use of statistics

Whereas change to a different connective, such as "In contrast". Whereas sounds awkward here the illustration symbolically depicts the intensity of the bushfires by having several hands stick up from the ground or ashes to represent
s grammar their change "their" to whoever you're talking about specifically, since it's too vague here desperate struggle for survival and help. More importantly, these black hands - most likely burnt from the fires - seem to be not only reaching out for help, but also, as primary school children are taught, raising their hands for answers.
