The Australia/Israel and Jewish Affairs Council has demanded ABC boss Michelle Guthrie explain a "massive omission" in its coverage of events on the Israeli border last week, accusing it of failing to adequately cover a Hamas rocket attack.

AIJAC executive director Colin Rubenstein said the public broadcaster had exhibited a "serious lack of balance" by declining to cover one of the largest rocket attacks against Israel in many years.

It adds to a barrage of complaints Ms Guthrie has fielded about ABC content from Communications Minister Mitch Fifield, in what some see as a pile-on against the broadcaster from hostile quarters.

International media reported at least 25 mortars were fired at Israel by militants on the Gaza Strip last Tuesday, in what the UK Independent newspaper described at "the single biggest attack from the Palestinian side since the 2014 Israel-Gaza war".
